Course Name : Anatomy and Biology of Shellfish

Code (Credit) :FSRM 3104 (1-1-0)

Program Outcome

PO1: Knowledge enhancement: Enhanced knowledge on concepts, essential facts, basics, principles and theories relating to fishery biology, biodiversity and aquatic environment, aquaculture, fish nutrition, fish physiology, genetics and biotechnology, fish processing, fisheries engineering, fish microbiology, fishery extension, economics, and biostatistics.

PO2: Professional and Entrepreneurial Skill development: Understanding the value and processes of life-long learning and professional enhancement and entrepreneurship development.

PO3: Critical thinking: After identifying the assumptions from the subject, take informed actions to frame the thinking and check out the degree to which these assumptions are accurate and valid, and look at our ideas and decisions (intellectual, organizational, and personal) from different perspectives.

PO4: Problem Solving: solve the problems from concerned disciplines using the knowledge, skills and attitude acquired from various disciplines in fisheries science.

PO5: Environment and Sustainability: Understand the issues of environmental contexts and sustainable development.

PO8: Team Work: Play effective roles in capture, culture, management, financial and marketing of fish produce.

Course Objectives

  • To understand the internal and external anatomy of a shellfish in detail
  • Knowledge on the various organs present, its functions and how they are functioning each other
  • To study the life history event of shellfishes, which dealt with the food and feeding habits, age and growth, maturation and reproductive strategies followed by embryonic and larval development of shellfishes.

Course Syllabus

Theory

Study of external and internal organization of commercially important crustaceans and molluscs. Digestive, respiratory, circulatory, nervous and reproductive systems. Food and feeding habits, growth, moulting, length – weight relationship. Reproductive biology, larval stages. Age and growth determination by direct and indirect methods.

 

Practicals

Study of Internal Organs commercially important crustaceans and mollusks. Study of Digestive, respiratory, circulatory, nervous and reproductive systems. Study of food and feeding habits - analysis of gut contents, age and growth, length - weight relationship and condition. Reproductive biology: maturity stages, spawning periodicity, fecundity and larval stages.
